    86The <a href="_WinAPI_SetWindowLong.htm">_WinAPI_SetWindowLong()</a> function creates the subclass by changing the window procedure associated with a particular window, causing the system to call the new window procedure instead of the previous one. An application must pass any messages not processed by the new window procedure to the previous window procedure by calling <a href="_WinAPI_CallWindowProc.htm">_WinAPI_CallWindowProc()</a>. This allows the application to create a chain of window procedures.
